What is wrong with my plums?

If the maggot problem persists use them for making Plum Wine, but add some Bentonite to the must to avoid getting a protein haze.

 

Here we go again,all seemed fine with mine,got quite a few fruit on it but tonight I noticed leaves dying off after a closer look I noticed the bark,any ideas guys ? Thanks x

 

Might be bacterial canker.

 

Just a few tips from prime plum-growing country, (anyone heard of pruneaux d'Agen?)
They need water at the critical stage of fruit-set. If they dry out at the roots, the fruit will drop.
They get aphids. Aphids poo all over the leaves hence the black deposits.
They get maggots. You can spray against both pests or, as an alternative, use pheromone traps early in the Spring to catch the male plum moths and stop the hanky panky that leads to the maggots! Soapy water and/or ladybirds, lacewings and wasps all sort out the aphids, but it takes nerves of steel and patience.
Bacterial canker, well, AFAIK there's not a lot you can do about that...prune out the affected branches in a dry spell in summer and burn them. When it's in the trunk, I'm afraid it's curtains.
On the bright side, whereas in the UK we all believe that you should never re-plant the same genus in the same spot, here they just bung a replacement in (probably with a healthy dollop of fertiliser and de-compaction of the soil) and off it goes!
Here endeth the lesson

 

Dont know much about plums, but wondering if you get gum oozing out the bark in places.

 

Thanks gang xx its looking like canker i must agree,ive just looked at back of it,it look like my small magnolia has it too ..oh well il fetch me saw x

 

Sorry, joolz68 Cherries, plums and apricots all seem to get it to some degree but it's sad when the trunk's affected.....
Didn't know that Magnolias are susceptible too

 

Im not sure they are susceptible too @noisette47 but it does have a small split in it bark so im just presuming...maybe its frost damage,ive not chopped it yet but the plum tree i sawn down on saturday x
